B) (2x-1)(2x-5)
X=1/2 or 5/2

You are rolling two dice at the same time. What is the probability of rolling a sum of 5 or 9?

baherus [9]

You can get a 5 by rolling :
1 and 4
2 and 3
3 and 2
4 and 1

You can get a 9 by rolling :
3 and 6
4 and 5
5 and 4
6 and 3

There are 36 possible outcomes, hence your probability is $\frac{4\cdot2}{36}=\boxed{\frac29}$
